The embodiment of the invention discloses a file encryption and decryption method and device and electronic equipment. The method comprises the steps: backing up the original name of a first file intoa preset file when the first file is encrypted; modifying the original name of the first file into a first random character; backing up the original part of information in the file content in the first file into a preset file; modifying the original part information in the file content in the first file into a second random character; when the first file is decrypted, obtaining an original name of the first file from a preset file; replacing the name of the first file of which the file name is the first random character with the original name of the first file; obtaining original part information in the file content of the first file from a preset file; and modifying partial information in the file content in the first file of which the partial information is the second random character into the original partial information in the file content of the first file. By adopting the embodiment of the invention, the data privacy can be effectively protected.
Description
technical field [0001] The present application relates to the field of computer technology, in particular to a method, device and electronic equipment for file encryption and decryption. Background technique [0002] With the development of the Internet and the increase in the speed of information dissemination, the issue of data privacy in the form of files is becoming more and more important to us. Usually, when naming a file, in order to facilitate indexing and accurately express the subject, the file name is usually a general description of the file content. However, the file name is the easiest to expose, and the subject or content of the file can often be determined through the file name. Therefore, how to effectively protect data privacy is a problem that people in the field are studying. Contents of the invention [0003] The embodiment of the present application discloses a file encryption and decryption method, device and electronic equipment, which can effectiv...
